Granted: 2009-01-20
Abstract: The invention provides a therapeutic agent for intractable vasculitis containing a hydantoin derivative represented by the formula (I) or a pharmaceutically acceptable salt thereof as an effective ingredient.   [In the formula, each of R1 and R2, which may be the same or different, represents hydrogen, an alkyl group or a cycloalkyl group; and each of X and Y, which may be the same or different, represents hydrogen, hydroxyl group, an alkyl group or an alkoxy group, or X and Y together represent an oxo group.] The compounds of the present invention significantly suppressed the generation of arthritis and arteritis (cutaneous ulcer and auricular infarcted necrosis) which were naturally developed in model animals (MRL/1pr), and further significantly elongated the survival rate of MRL/1pr mice. Consequently, the compound of the invention having low toxicity and less side effects is very useful as a highly safe therapeutic agent for intractable vasculitis such as malignant rheumatoid arthritis.

Abstract: An electrical cable has helically attached bristles for supporting the electrical cable when pulled through a string of coiled tubing to connect to an electrical submersible pump. The electrical cable and helically attached bristles have a circumscribed diameter greater than the inner diameter of the coiled tubing. The bristles deflect in a direction opposite the direction of pulling the electrical cable so that they grip the wall of the coiled tubing. The bristles apply a resistive frictional force to the wall of the coiled tubing, thereby transferring the weight of the electrical cable to the coiled tubing.

Abstract: A method of treating vented or fugitive methane streams, comprising the steps of providing two or more thermal catalytic converters coupled with pressure sensitive valves to form a catalytic converter assembly and at least one pilot heat source to initiate a catalytic reaction within one of the thermal catalytic converters. When a vented or fugitive methane stream is channelled through the catalytic converter assembly, the catalytic converters start up and shut down in sequence in response to variations in the supply of methane gas. Preferably, heat generated in initiated catalytic converters is used to sequentially initiate a catalytic reaction in remaining adjacent uninitiated catalytic converters.

Abstract: A force multiplying device is provided for use in conjunction with a balancing system for moving a load from an elevated position and to a predetermined lower position. The balancing system includes an extendable cable with a free end adapted to be secured to and exert an upward force on the load. The device includes a base which is secured to the load and a first lever pivotally secured at an intermediate point to the base about a generally horizontal axis. A fixed length flexible member has one end secured to a first end of the lever and a second end fixedly secured to a support position above the load. The length of the flexible member is such that the flexible member is in a fully extended position when the load is in the predetermined lower position. An elongated rocker arm has a first end in abutment with the base while the cable from the balancing system is secured to a second end of the rocker arm. A second end of the lever is pivotally secured to an intermediate point of the rocker arm so that, as the load nears the predetermined lower position, the first end of the lever pivots upwardly and simultaneously pivots the second end of the rocker end downwardly to thereby exert an increased downward stroke on the cable, and a corresponding upward force on the load.     By construction, the length of each rocker and lever arms is such that the distance between the flexible member and the extendable cable is minimal.     Furthermore, two systems like that can be symmetrically combined in such a way that the center of gravity of the load to be balanced remains in the same plane that the pair of flexible members and extendable cables, avoiding by that any swinging of the load during its entire stroke.
